hello, the firefox homepage doesn't contain any google cookies.

i guess that what you are seeing (because this is happening after you start firefox as well) is the malware/phishing protection feature in firefox downloading a list of known bad domains from google's safebrowsing service this will create one cookie. however this particular cookie is sandboxed and separated from all other cookies, so i cannot be used by google to track you during webbrowsing. for details see bug 897516...

Hello philipp

I am not sure this is what is happening.

I checked this again and this is how it goes. About 5 seconds after Firefox is fully loaded the little pop-up appears saying "Cookies from Google.com self destructed". This closes after a few seconds followed another 5 seconds later by "TRACKERS and Cookies from Google.com self destructed" (My capitalizing of the word TRACKERS). So, Google cookies are destroyed twice, indicating at least 2 cookies. Google trackers also get in to my browser which has to be destroyed by the add on.

Regards, Christine

please try to disable malware and phishing protection in the firefox security panel once and see if the behaviour changes after a restart.

This was done but behavior not changed. I did some more looking around and found this. I have Linux and Windows dual boot set up on one machine. This problem is only on the Linux system. I logged into Windows and checked. No google cookies or trackers appear in Firefox there!

Firefox on both Linux and Windows are identical (14.0.4). Options and preferences are also both at default settings. What could we do next?

on your linux partition could you go to the firefox menu ≡ > help ? > troubleshooting information, copy the contents of that page and paste them here into a reply on the forum? this might give us a clue what is going on...

Here is everything except what is in the Profile Directory. Christine

maybe one of your privacy addons is setting a google tracking opt-out cookie?

I checked once again. My Firefox in windows OS has all the addons that the one in Linux has. Windows Firefox shows no cookie or tracker removing pop up.

I have set Firefox as my home page. When it opens it opens the Firefox Home page. One of my add ons' is Self Destructing Cookies. A few seconds after opening, Cookies and trackers from Google.com are being removed by this add on. Mind you this is Firefox Home page before going to any web site. I don't even have google chrome or any other google application. This is very disconcerting. Can you please find a way to block google from mucking with Firefox? Than you

Maybe Firefox is not set as the Default browser. Have Windows7 64 needed to type at the start menue Default browser and nominate same

Firefox is definitely set as my Default Browser. For about 10 years I always had Firefox and nothing else as my default browser. In fact it is the only browser I have in my computer!

Google chrome was already installed on this Linux OS. The first thing I did was uninstall it. I don't use anything of Google including their 'google search'. What is worrying is, all that I have described happens on Firefox home page without connecting to any web site.
